I recently bought and opened a box of 2007 SP Authentic and pulled out a redemption card for a 2007 SP Authentic Baseball By The Letter Rookie Signatures CD#150 Daisuke Matsuzaka card. I understand the redemption period is long over, but what happens to those cards that aren't redeemed? Did Upper Deck destroy the cards? Have been out of the hobby for awhile and know there have been many changes in the industry. Any information would be great.
